  248.                            <p class="info">This research explores the evolution of game monetization models in mobile games, with a focus on player preferences and developer strategies over time. By examining historical data and trends from the mobile gaming industry, the study identifies key shifts in monetization practices, such as the transition from premium models to free-to-play with in-app purchases (IAP), subscription services, and ad-based monetization. The research also investigates how these shifts have impacted player behavior, including spending habits, game retention, and perceptions of value. Drawing on theories of consumer behavior, the paper discusses the relationship between monetization models and player satisfaction, providing insights into how developers can balance profitability with user experience while maintaining ethical standards.</p>
